But generally you don't use 180 degree rotation with airplanes, 120 degrees is plenty enough.
We don't have any documentation on it that I'd be able to post, the HPP-21 should have a general guide that came with it.
Thanks I got most of it figured out last night playing with it. If you couple enlighten me on the End Points. Example if I go into Program , set the center as it comes out of the box, and then grab the Handle and drag it Right or Left it spits out a number from 0 to 215, and 0 - -215. I stretched it out to 215 and -215 and got the 180 degree rotation. Is there any kind of Scale?
I think I got close by doing simple ratios that 90 degrees = 215, thus 45 degrees os 107/108. Put another way if I wanted to keep 120 degree Rotation to set the handles to 143 and - 143.
Am I on the right track? Seems to be close.
